That is not a memory problem. It is a timing problem. IM VOCA brings every word back right before you forget it.
Any vocabulary book, any textbook, even your own handwriting. One photo.
It pulls out every word with meanings, pronunciation, example sentences and word origins.
Each word comes back six times, on the days you were about to forget it.
Six reviews, spaced further and further apart, following the Ebbinghaus forgetting curve. You never pick what to review — the app does. Flipping a card is not enough: you have to answer the quiz for the review to count.
Stop typing words one by one. Photograph the page you are already studying.
The sense that fits the sentence you photographed — plus word origin, synonyms and derivatives.
4,800 words graded CEFR A1 to C2, free — with meanings in Korean, Chinese, Japanese or Spanish. Studying from English? Build your own book from a photo instead.
Not sure where to start? Answer a handful of words and the app picks your level.
One notification on the day a review is due. No streaks to guilt you, no daily spam.
Native pronunciation for every word and example sentence.
Running a school or academy? The director's account is free. See the plan for teams.
The app interface is available in English, Korean, Chinese, Japanese and Spanish. The official wordbooks teach English, and their meanings are written in Korean, Chinese, Japanese or Spanish — so they fit learners reading one of those. English meanings are not written yet. Whatever your language, you can build your own wordbook in any language pair by photographing a page.
Only if you want one. The camera turns any page you already own into a wordbook, and typing words in by hand is unlimited and free. The official wordbooks — 4,800 words across twelve CEFR levels — are free too, with meanings written in Korean, Chinese, Japanese or Spanish; pick the one you read and they are yours.
You do not build the deck. Photograph a page and the cards exist, complete with meanings, example sentences and pronunciation. The scheduling is fixed and automatic — nothing to configure.
Nothing is lost. Overdue reviews wait for you instead of resetting. There is no streak to break and no penalty.
Sign in with the same account and your words, progress and review schedule follow you — across devices, and between the web and the app.
Thirty seconds to sign up. No card.
